ABSTRACT

Provided is a refrigerant composition that has a low GWP; is non-flammable or mildly flammable; and has a refrigerating capacity (Cap) and/or coefficient of performance (COP) equivalent to or higher than those of traditional refrigerants, such as R-134a, R-410A, R-123, or R-404A, when used as an alternative refrigerant for these traditional refrigerants. Specifically, provided is a refrigerant composition containing FO-1216 and a hydrofluoroolefin, wherein the hydrofluoroolefin is at least one member of HFO-1234ze and HFO-1243zf.

TECHNICAL FIELD

The present disclosure relates to a refrigerant composition, inparticular a refrigerant composition that has low global warmingpotential (GWP); is non-flammable or mildly flammable; and has arefrigerating capacity (Cap) and/or coefficient of performance (COP)equivalent to or higher than those of traditional refrigerants, such asR-134a, R-410A, R-123, and R-404A.

BACKGROUND ART

Refrigerants for use in a range of air conditioners, coolers, etc.(including working media for thermal cycling, without a limitation tothose for cooling), are required to have characteristics, such as lowGWP, low flammability (preferably non-flammable or mildly flammable),and high Cap and/or COP. In particular, from the standpoint of GWP,hydrofluoroolefin (HFO) refrigerants have been used as alternatives fortraditional hydrofluorocarbon (HFC) refrigerants.

However, the use of an HFO refrigerant alone still leaves room forimprovement in terms of flammability, although its low GWP of less than10 is an advantage. To address these circumstances, attempts have beenmade to mix an HFO refrigerant with a known non-flammable refrigerant tomake the entire mixture non-flammable. However, adding a knownnon-flammable refrigerant increases GWP. Thus, refrigerants that achieveboth GWP and low flammability have yet to be developed.

There are documents related to the present disclosure. These include,for example, the following Patent Literature 1 to 4.

PTL 1 relates to a heat transfer composition, and claim 1 thereofdiscloses “[a] heat transfer composition comprising (i)trans-1,3,3,3-tetrafluoropropene (R-1234ze(E)), (ii) a second componentselected from difluoromethane (R-32), propene (R-1270), propane (R290),and mixtures thereof, (iii) a third component selected frompentafluoroethane (R-125), 1,1,1,2-tetrafluoroethane (R-134a), andmixtures thereof, and optionally (iv) a fourth component selected fromfluoroethane (R-161), 1,1-difluoroethane (R-152a), and mixturesthereof.”

The heat transfer composition of PTL 1 is a combination of R-1234ze(E),which is an HFO refrigerant, with the second component, the thirdcomponent, etc. Although the composition includes a non-flammablecomposition (claim 22), its GWP is less than 2800, and preferably lessthan 1500 (claim 17). In actuality, a GWP of more than 1400 and lessthan 1500 is the limit.

PTL 2 relates to a fluid composition, a refrigerant composition, etc.Claim 1 thereof discloses a fluid composition that is a composition (I)comprising at least one component (A) selected from the group consistingof alkanes, halogenated alkanes, and alkenes, and at least one component(B) selected from halogenated alkenes; or a composition (II) comprisingat least two components (B) selected from halogenated alkenes (excludingcomposition (I)), wherein the combustion inhibiting effect is at least10%.

The composition (II) contains at least two components (B), and thecomponent (B) includes various HFO compounds and other compounds (claim8). The fluid composition, refrigerant composition, and the like of PTL2 are disclosed as having a combustion-inhibiting effect of at least10%. However, the inhibition of flammability still leaves room forimprovement, and the demand for non-flammability or mild flammability isnot satisfied. PTL 2 also does not suggest the quantitative relationbetween the components for achieving a low flammability of the entirecomposition.

PTL 3 relates to a working fluid (e.g., a refrigerant) containing aperfluoropropylene (hexafluoropropylene: FO-1216); and discloses on page2, upper-right column to lower-left column, that the perfluoropropylenecan be mixed with another compound having a boiling point that isdifferent by ±50° C. from the boiling point of the perfluoropropylene,such that the amount of the other compound is up to 50% by weight of theperfluoropropylene. PTL 3 lists examples of substances that can beadded, such as chlorofluorocarbons, ethers, and amines. However, PTL 3nowhere suggests GWP of the entire mixture, or the quantitative relationbetween the components for achieving a low flammability.

PTL 4 relates to an alternative refrigerant containinghexafluoropropylene (FO-1216), and the claims thereof list examples ofnon-flammable refrigerants that are a combination of FO-1216 withanother component. However, PTL 4 nowhere suggests the quantitativerelation between the components aiming to reduce the GWP of the entiremixture.

BRIEF DESCRIPTION OF DRAWINGS

FIG. 1 is a diagram illustrating an experimental apparatus for examiningflammability (flammable or non-flammable).

DESCRIPTION OF EMBODIMENTS

The following describes the refrigerant composition according to thepresent disclosure in detail.

The refrigerant composition according to the present disclosure is aspecific mixture containing FO-1216 (hexafluoropropylene), which issuitable for use in a refrigerant (including working media for thermalcycling, without a limitation to those for cooling), has a low GWP; isnon-flammable or mildly flammable; and has a refrigerating capacity(Cap) and/or coefficient of performance (COP) equivalent to or higherthan those of traditional refrigerants, such as R-134a, R-410A, R-123,or R-404A, when used as an alternative refrigerant for these traditionalrefrigerants.

The refrigerant composition according to the present disclosure can bebroadly divided into the following refrigerant compositions ofembodiments 1 to 4. The technical meanings of “non-flammable” and“mildly flammable” in the present specification are as described below.

In the present specification, whether a composition is flammable ornon-flammable was confirmed by performing a combustion test on a mixturerefrigerant in relation to the composition ratio, based on ASTM E681 (anASHRAE method), using a flammability experimental apparatusschematically illustrated in FIG. 1 (the following is illustrated: A.charging line, B. sampling line, C. thermometer, D. pressure gauge, E.electrodes, and F. stirring blade (made of PTFE)). A combustion angle of90° or less was determined to be non-flammable.

A combustion angle of more than 90° was determined to be flammable basedon the flammable range test. In particular, “mildly flammable” in thepresent specification was distinguished as compositions with a burningrate of 10 cm/s or less, among those determined to be flammable, inaccordance with the burning rate test of ASHRAE 34-2010.

Refrigerant Composition of Embodiment 1

A refrigerant composition according to embodiment 1 contains FO-1216 anda hydrofluoroolefin. The hydrofluoroolefin is at least one member ofHFO-1234ze (1,3,3,3-tetrafluoropropene) and HFO-1243zf(3,3,3-trifluoropropene).

The refrigerant composition according to embodiment 1 preferablycontains FO-1216 in an amount of 2 mol % or more based on the totalamount of FO-1216 and the hydrofluoroolefin (hereinafter, “thehydrofluoroolefin” refers to at least one member of HFO-1234ze andHFO-1243zf) taken as 100 mol %.

The refrigerant composition according to embodiment 1 contains an HFOrefrigerant as the main refrigerant. Being a mixture of FO-1216 and thehydrofluoroolefin, the refrigerant composition has a low GWP (preferably300 or lower); is non-flammable or mildly flammable; and has arefrigerating capacity (Cap) and/or coefficient of performance (COP)equivalent to or higher than those of traditional refrigerants, such asR-134a, R-410A, R-123, or R-404A, when used as an alternativerefrigerant for these traditional refrigerants. FO-1216 is anon-flammable substance in the present specification, and is positionedas a flammability-reducing agent (this position applies to therefrigerant compositions of other embodiments).

Regarding the content of FO-1216 and the hydrofluoroolefin, FO-1216 ispreferably present in an amount of 2 mol % or more based on the totalamount of FO-1216 and the hydrofluoroolefin taken as 100 mol %; in otherwords, the hydrofluoroolefin is preferably present in an amount of 98mol % or less based on the total amount of FO-1216 and thehydrofluoroolefin taken as 100 mol %. In particular, it is morepreferred that FO-1216 be present in an amount of 90 to 10 mol %, andthat the hydrofluoroolefin be present in an amount of 10 to 90 mol %. Arefrigerant composition containing FO-1216 and the hydrofluoroolefin inan amount within these numerical ranges can easily have a low GWP (inparticular 10 or less); become non-flammable or mildly flammable; andhave a refrigerating capacity (Cap) and/or coefficient of performance(COP) equivalent to or higher than those of traditional refrigerants,such as R-134a, R-410A, R-123, or R-404A, when used as an alternativerefrigerant for these traditional refrigerants.

The refrigerant composition according to embodiment 1 preferably has aGWP of 300 or lower, and more preferably 150 or lower. Although FO-1216is positioned as a flammability-reducing agent that makes the entirecomposition non-flammable in the refrigerant composition according toembodiment 1, the refrigerant composition may also contain otherflammability-reducing agents in combination, as long as the compositioncontains FO-1216 as an essential element, and the effects of the presentdisclosure are not impaired.

Further adding a hydrofluoroether (HFE) to the refrigerant compositionaccording to embodiment 1 imparts the following characteristics to therefrigerant composition: even if the refrigerant composition leaks froma refrigerant pipe, the refrigerant composition remaining inside thepipe can easily maintain the non-flammable characteristics, whilemaintaining the low-GWP characteristics (300 or lower). HEE for use is anon-flammable substance in the present specification. Regarding thecontent of HFE, HFE is preferably present in an amount of 2 mol % ormore based on the total amount of HFE, the hydrofluoroolefin, andFO-1216 taken as 100 mol %.

HFE is, for example, at least one member of trifluoromethyl1,2,2,2-tetrafluoroethyl ether (HFE-227me), difluoromethyl1,1,2,2,2-pentafluoroethyl ether (HEE-227mc), trifluoromethyl1,1,2,2-tetrafluoroethyl ether (HFE-227pc), difluoromethyl2,2,2-trifluoroethylether (HFE-245mf), and2,2-difluoroethyltrifluoromethyl ether (HFE-245pf). In particular,HFE-227me is preferable.

For example, the use of HFO-1234ze (boiling point: about −19° C.) as thehydrofluoroolefin, and HFE-227me (boiling point: about −10° C.) togetherwith FO-1216 (boiling point: about −30° C.) in the refrigerantcomposition according to embodiment 1 imparts to the resultingcomposition characteristics such that even if the refrigerantcomposition leaks from a refrigerant pipe, the refrigerant compositionremaining inside the pipe can easily maintain the non-flammablecharacteristics, while maintaining the low-GWP characteristics (300 orlower).

This is due to the fact that even if a refrigerant composition leaksfrom a refrigerant pipe, combining a flammable HFO refrigerant (e.g.,HFO-1234ze: the main refrigerant) with a non-flammable refrigerant thathas a lower boiling point than the main refrigerant (FO-1216) and anon-flammable refrigerant that has a higher boiling point than the mainrefrigerant (e.g., HFE-227me) allows the non-flammable refrigerant thathas a lower boiling point than the main refrigerant to leak first,leaving the non-flammable refrigerant that has a higher boiling pointthan the main refrigerant, and thus maintaining the non-flammablecharacteristics of the refrigerant composition remaining inside therefrigerant pipe.

In this case, the non-flammable refrigerant that has a lower boilingpoint than the main refrigerant (FO-1216) is preferably present in anamount of 1 mol % or more in the refrigerant composition (before leak),and the non-flammable refrigerant that has a higher boiling point thanthe main refrigerant (e.g., HFE-227me) is preferably present in anamount of 1 mol % or more in the refrigerant composition (before leak).The difference in boiling point between the non-flammable refrigeranthaving a lower boiling point than the main refrigerant and the mainrefrigerant is preferably 5° C. or more, and more preferably 5 to 15° C.The difference in boiling point between the non-flammable refrigeranthaving a higher boiling point than the main refrigerant and the mainrefrigerant is preferably 5° C. or more, and more preferably 5 to 15° C.

From the viewpoint above, the present disclosure includes a refrigerantcomposition such that even if the refrigerant composition leaks from arefrigerant pipe, the refrigerant composition maintains itsnon-flammable characteristics. More specifically, the present disclosurealso includes “a refrigerant composition that contains a flammable HFOrefrigerant as the main refrigerant, 1 mol % or more of HFO-1216(non-flammable refrigerant) having a lower boiling point than theflammable HFO, and 1 mol % or more of a non-flammable refrigerant havinga higher boiling point than the flammable HFO.” The HFO refrigerant asused here is not limited to the hydrofluoroolefin according toembodiment 1, and a wide range of known HFO refrigerants are applicable.
